3.0 MAIN VALVE MAINTENANCE
(REFER TO FIGURE 3)
Normal valve maintenance will be to only
clean the parts. It may also be necessary
to replace the seat. The piston seal should
not need to be replaced. If the piston seal
is removed, a new seal must be installed.
The piston can be removed from the
cap/liner by pulling the piston out or by
pushing it out with a rod through the hole
in the top of the cap/liner.
No lubricant is required on the piston
seal. A small amount of thread sealant
should be used on the pipe threads to
prevent leakage. Teflon
®
tape is
recommended.
The piston should be assembled to the
cap/liner and the two parts should then be
assembled to the valve body. The piston
can be prevented from sliding out of the
cap/liner during assembly by covering or
plugging the hole in the top of the
cap/liner.
For marine service, the bolts in the
main valve and pilot exposed to the
environment should be replaced
during routine maintenance every five
